Does it matter if WrapFlagsTy gets extended to cover more cases though? Surely, the trunc op can still use a subset of WrapFlagsTy? In my mind, the only reason for having a new TruncFlagsTy would be if the trunc op had a trunc-only flag. I think it's simpler to reuse the existing WragFlagsTy for now.
